Shhh, be very quiet, there is FUNGUS among us!  Light up fungus, which makes it so much better!  This amazing hat resembles a red mushroom with white spots.  Except on this mushroom, the spots light up and glow!  Hat is foam backed velour and has a velcro size adjuster on the inside.  The battery pack is hidden inside the hats lining.  Requires 2 AAA batteries and includes demo batteries.    The lights show through the vinyl circles on the hat.  One size fits most adults and teens.  Great for a forest creature, Super Mario costume or just when you are feeling a little toxic....
